Specification of Letters Patent.

Application filed December 27, 1910. Serial No. 599,560.

To all whom imag/ concern:

Be it known that I, ALBERT H. SissoN, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certainV new and useful Improvements in Car Construction, of which the following is a specification.

My invention relates to car construction and refers particularly to aA novel form of car siding.

It is well known that in car construction a result which has long been sought consists in obtaining for the siding a combination of a maximum strength with a minimum weight. I have found that very satisfactory results are obtained by forming the sheathing, preferably where it occupies a position below the car window sills and serves as a girder, with strengthening integral cross members. l have found that these cross members may be formed in a variety of ways. For example, apertures in the sheathing may be punched so that the entire body of the same may remain in a single plane, or the punching may be performed in such manner that the cross members may each have an inwardly disposed flange, or there may not only be these inwardly disposed flanges but a second flange may be provided on each edge which occupies a plane parallel to the plane of the main body of the'sheathface lying ijn more than one vertical plane.

A further feature of my invention con.- sists in the use of a novel finishing sheet preferably placed outside of the side sheathing just described, which sheet 1s readily removable from the car.

The variousadvantages of my invention will be, more clearly understood by reference to the accompanying drawings which represent a preferred embodiment of my improvements and in which:

Figure 1 is a fragmentary-side elevation of a car with the inner sheathing and finishing sheet removed. Fig. 2 is a fragmentary longitudinal section through the side Vsheathing. Fig. 3 is a section similar to Fig. 2 but showing a' modified construction. Fig. 4 is a section similar to Fig. 2 showing a second modified construction. Fig. 5 is a section Fig. 7 is a section similar to Fig. 6 but show-.

ing a slightly modified form of construction. Fig. 8 is an enlarged fragmentary trans# verse vertical section throughthe lower portion of the side wall of the car below the window and showing a finishing strip added to the framing shown in detail in the other figures.

Extending downwardly from the sill line 10 is the side sheathing 11 which is fastened to the car body by any of the well known methods. Between the car posts 12 this side sheathing 11 is formed with oblique trusslike members 13 which may be made in a variety of ways. For example, as shown in Figs. 1 and 2, apertures 14 may be formed in the side sheathing, the flanges 15 extendresented Maine, isis. l

ing inwardly from both the oblique truss members 13 and the portions 16 opposite the car posts 12. It will be noted that, as shown in Fig. 1, the truss members 13 toward the right hand end of the car extend downwardly and in an oblique direction from left to right, whereas in the central part of the car such truss members alternate with those extending downwardly from right to left and toward vthe left hand end of the car truss members 13 extend from right to left.

As clearly Shown in Fig. 3, the apertures 14 may be formed without any flanges on the oblique truss members 13 or thewportions 16 opposite the car posts. Again as shown in Fig. 4c, the apertures 14 may be punched in -such manner that not only are the inwardly extending flanges 15 formed, but

also fianges 17 whichlie in a plane parallel with the main body of the sheathing 11..

A still further modified form ofV construction is shown in Fig. 5 in which no apertures are punched, but 'a plurality of panels 18 are formed by depressing portions of the surface of the sheathing 11.

It will be clear to those skilled in the art that by the various forms of construction which I have mentioned the maximum degree of strength is obtained with the minimum weight of the sheathing 11.

.The construction of the car above the openings 19 occupied by the window sashes,l

forming continuations of the posts 12 and the letter-board being indicated at 21.

- side sheathing ,11 and 22 form girder plates of the truss structure ofthe carand that the panels and recesses formed therein serve to materially reinforce the same without adding to the Weight.

In Fig. 8 I have shown the finishing sheet 25 in position outside of the side sheathing ll. As indicated, this iinishing sheet 25 is ordinarily in two sections, the upper extending downwardly from the belt rail 26 to the guard rail 27 and the second extending from the guard rail 27 downwardly to the angle iron 2S to which the side sheathing 11 is also attached. This finishing sheet has the double function of providing an insulating air space between itself and the side sheathing l1 land also preventingr the injury to the side sheathing l1 when Atheshafts of wagons or the like come in contact with the surface of the car, as often happens in the case of ordinary. street cars. On account of being attached by the rivets or bolts ing sheet can be readily removed in case of injury. The remaining parte shown in Fig. 8 are of well known construction and do not form the subject matter of the present invention.

It will be clear to those skilled in. the art that considerable change may be made in the preferred construction which l have de l scribed without departing from the spirit of my invention. What I claim l. iin a car construction, the combinationof an, inner sheathing having a recess theredescribed. l A

3. In a car construction, the combination of an outer-sheathing, a belt rail, a guard raii extending outwardly beyond the outer sheathing, a supportingl member, and readily removable iinishing sheets outside of said outer sheathing and extending from Said belt rail to said guard rail and from said guard rail to said supporting member, thereby forming an insulating air space between the outer sheathing and said finishing sheets, substantially as described.

e. In a car construction, a sheathing having obliquely disposed strengthening members integraliy formed in and a Vremovable finishing sheet outside thereof substantially as described.

5. In a car construction, a sheathing of sheet metal paneled to form intermediate obliquely disposed integral strengthening members, and a substantially plane finishing sheet secured outside Ithereof substantially as described.
